Former Finance Minister P Chidambaram struck a defiant note at his first press conference since walking out of Delhi's Tihar Jail late Wednesday evening, declaring he had emerged "stronger in spirit and body" after 106 days of custody. Mr Chidambaram, 74, who has spent more than two months in jail, told reporters today that "my neck is stronger, my spine is stronger, my head is stronger" after sleeping on a wooden board (in jail).
